VALVE-MANIPULATOR FOR RADIATORS.

To all tti/wm t may concern Be it known that I, JED W. PRIOR, a citizen of the United States', residing at Burlington, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Valve-Manipulators for Radiators, of which the following is a speciiication, reference being had therein to the accompanying drawing.

rIhis invention relates to certain new and useful improvements in valve manipulators for radiators, and is especially adapted to be used in connection with concealed radiators used in indirect heating; the object being to provide a manipulator by means of which the valve can be readily actuated without having to insert the hand through an opening in the cover of the chamber containing the radiator.

Another object of my invention is to provide a valve manipulator which is exceedingly simple and cheap in construction and one which can be readily attached to an ordinary form of radiator valve, so as to enable the same to be readily manipulated.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof deined by the appended claims.

In the drawing- Figure 1, is an elevation of my improved construction of manipulator showing the application of the same to a radiator arranged within a chamber; and

Fig. 2, is a perspective showing the application of the same, the hand wheel being in position on the closure of the chamber to allow the same to be readily operated.

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawing, 1 indicates a chamber formed in the wall, 2 the radiator, 3 the radiator valve and 4 the closure for said chamber, which is herein shown formed of wood and is provided with air inlet openings adjacent its lower edge and outlet openings adjacent its upper edge to allow the heated air to escape from the chamber, the above description being given so that the operation of my improved construction of manipulator can be readily understood when connected to a concealed radiator.

The closure 4 herein shown is of wood, but it is, of course, understood that it can be Specification of Letters Patent. Patented Dec, 24 918 Application mea March 17,1916. seria1N0.s4,95o. Y i Y formed of marble, brick or any other material, and it is provided with an opening 5 in which an internally threaded sleeve 6 is arranged having an annular flange 7 engaging the face of the closure 4 and provided with a circular socket 8 in which is adapted to be arranged the key portion 9 of a hand wheel 10.

Working in the internally threaded por.- tion of the sleeve 6 is an externally threaded bearing sleeve 11 on which is mounted a washer 12 and a nut 13 so as to clamp the flange 7 of the sleeve 6 against the face of the closure 4 and it will be seen by this construction that I have provided means for clamping the sleeve 6 in position in closures of diferent thicknesses.

Revolubly mounted within the bearing sleeve 11, is an operating rod 14 having a square portion 15 to receive the key portion 9 of the hand wheel 10, the end of said square portion being provided with a threaded bore into which extends a screw 16 for locking the key in position thereonwithin the socket 8 of the flange 7. In vorder to prevent the operating rod 14 from moving lengthwise Within the bearing'sleeve 11, I provide the same with a transverse pin 17 which works Within an annular groove 18 formed in the sleeve 6 so as to relieve the key of the end thrust of the shaft.

Secured on the end of the rod 14 by a set screw is a coupling 19 which is preferably provided witha threaded socket into which extends a nipple 20 which is locked in one of the coupling members of a universal joint 21 by a pin as clearly shown'.

By providing a threaded nipple in connection with the coupling 19 and universal joint 21, the distance between the coupling and universal joint can be adjusted.

The universal joint 21 is connected to a universal joint 22 by a connecting rod 23 and in constructing` these members, the rod 23 is preferably formed integral with the members of the universal joints at its ends, although, of course, the particular construction and manner of connecting these members can be varied without departing from the spirit of my invention.

ne of the members of the universal joint 22 has secured therein by a pin, a threaded nipple 24 which is mounted within a threaded bore of a coupling member25 and locked by a set screw' as clearly shown, so that the distance between the counling and universal joint can be adjusted.

The coupling member carries a sleeve 26 having a transverse pin 27 V adjacent its' lower end which passes through a slot formed in the neck 28 of a stirrup 29 in order to provideY a sliding connection between the sleeve and neck of the stirrup.

Secured Within the stirrupQQ is a valve stem 30 of the valve, said stirrup being preferably provided with an opening in its base through which the valve stem 30`passes and 'Whichi's secured by a screw 31 and vvvasulierrg-as clearlyshovvnin l.

u., member as .the'valve rises` in. opening the saineandto drop Within' thecoupling'mernber asl the valve is closed.

From the foregoing description, itr will be I seen that I haveprovided a valve manipulator which'. is so constructed that the same can be readily attachedto the ordinary forni of radiator valve now in use and'mounted Withiny the closure. of 'the chamber in which the radiator is'a1'1 anged,l soas 'to allow-'the valve ofthe. radiator to: be .manipulated throu'tghV the exterior.. of'. the chamber' by simply turnng'the hand wheelwhich cor- 'responds to the hand Wheel noW in use on radiator valves.

I claim:

l. A valve manipulator, comprising a bearing sleeve having means for securing the same in a support, an operating Vrod mounted in said bearing' sleeve, a -Wheel having a key portion connected t0 said operating rod, a'coupling carried by said operating rod, a nipple adjustably mounted in said coupling, a second rocha universal joint connecting'thesecond rod tosaid nipple, aY universal joint 'carried bythe second rod, a nipple connected to said `last-mentioned universaljjoinmva coupling connected to'said nipple', a stirr. p slidably'inountedwithin said last- Inentioned coupling, vvand means for.connect ing saidstirrup to the valve of 'a radiator.

2. In a valve manipulator-for radiators, the combination with a radiator valve having'a valve stein, of a. stirrup fixed on said valve stem, a couplinghaving'a sliding con.- nectio'n'with said stirrup, an operatingrod, a bearing for said operating rod', a' hand Wheel having la key connected to said operating' rod, and a universal connection: b'etween said operating rod and coupling;

In testimony Whereof'I hereunto aiiix my signature iny the presenc'eof two Witnesses.
